DNA Test:  Study Guide

 

1. A nucleotide is about to be added to a growing strand of DNA. What factor determines which type of nucleotide will be added?

 

2.

During the process shown above, the two strands of one DNA molecule are unwound. Then, DNA polymerases add complementary nucleotides to each strand which results in the formation of two identical DNA molecules.

This process is known as DNA _______.

 

3. The DNA of a cell is organized into structures. What are these structures called?

 

 

4. When a molecule of double-stranded DNA undergoes replication, it results in

 

 

5. A parent DNA molecule replicates, resulting in two daughter DNA molecules. Which of the following is true?

 

 

6. How are complementary strands of DNA held together?

 

 

7. During the interphase stage of the cell cycle,

 

8. In which stage of the cell cycle does DNA replication occur?

 

9. During DNA replication, a primer attaches to a template strand of DNA and begins a new strand. After the primer has attached, an enzyme extends the new strand of DNA by adding nucleotides that correspond to the nucleotide sequences in the template strand.

Which enzyme is responsible for adding nucleotides to the growing DNA molecule?

 

 

10. The nucleotide of DNA is one large molecule composed of three smaller molecules. Which of the following sets of molecules bond together to form a nucleotide?

 

11. Hereditary information is found in _______, which are located in the _______ of the cell.

12. The process of DNA replication is biologically significant because it allows the cells of living organisms to

 

13. Which of the following correctly describes the components of DNA?

 

14. DNA replication results in two identical DNA molecules. What role do DNA helicases have in DNA replication?

 

15. The genetic information that is passed from a parent to its offspring is found in _______.  

17. The sequence of bases on one strand of a DNA molecule is ATTGCCCATG. What will be the sequence on the complementary strand?

 

18. Which of the following molecules is the subunit of DNA that links together to form strands of DNA?

 

19. Which choice below correctly summarizes the base-pairing rules in DNA?

 

20. After the process of _______ occurs, each daughter cell receives an exact copy of the parent cell's DNA.

 

21. Before a cell divides, what happens to the genetic information in that cell?
